Data recovery and disk repair questions and discussions related to old-fashioned SATA, SAS, SCSI, IDE, MFM hard drives - any type of storage device that has moving parts

Hi gents,
I have a HD203WI here, where both S-list and T-list are corrupt. Access to parts of the data fails due to translator failure (still copying, maybe 80% are ok).
All 6 heads are ok, S.M.A.R.T. reports 148 reallocated and 1 uncorrectable sectors after only 48h operation time.
Rebuilding S-list from T-list and backwards failed, because both are faulty (e.g. terminal output shows head 7 read failure!)
Has anybody an idea, how to clean up, or rebuild the defect lists? Is there a command available, where the translator can be rebuilt? (I know, that Samsung is not Seagate...)
I can provide logs later, now I'm sitting at my office PC.
Thanks in advance!
Thomas
PS: Happy new Year!!!

Hi BlackST,
thanks for prompt reply.
After copying data over night with PC3K, I have some more details:
- Data from LBA 0 - 192268814, and 3850905787 - 3907029167 (end of disc) copied. Somwhere between clicked on sectors, they're readable.
- Defect List is strange, because the disc has only 6 heads (0...5). Defect list shows entries for head 6+7, which will be claimed by firmware:

Is it possible to erase whole firmware area, write back all sectors except defect lists, and scan defects?
I have enough experience with Seagate and WD translator issues, but (still) not with Samsung.

Perfect. Let's switch to PM mode only.

<switch>
(I prefer static translators...

Hi, I got it:
Main problem was, that Samsung uses a dynamic translator. Means, translator will be generated using defect lists. But T-list was corrupt. (Seagates translator is here more friendly to repair..)
With new PC3000-Update I was able to rebuild T-list. Now I have full access to disc.
Of course this is a case for Samsung warranty service.
Kind regards,
Thomas
